GARRETT WALLACE POOLE, OF NEWARK, NEW JERSEY, ASSIGNOR TO ANNIE THURSTON POOLE, OF SAME PLACE.

ADJUSTABLE BOOK-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 510,090, dated December 5, 1893.

Application filed March 31, 1893.

To all whom it may concern.-

Be it known that I, GARRETT WALLACE POOLE, a citizen of the United States, residing in Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Adjustable Book- Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon,'which form a part of this specification.

My invention relates to a new and useful improvement in adjustable music or book supports, especially adapted to be used on chairs or similar pieces of furniture.

The object of this invention is to'provide a book or music support of simple, strong and durable construction, adjustable to any 'desired position, and capable of being folded together and turned under or within the piece of furniture, to which it is attached.

The invention consists in the improved book or music support, in its connection with the piece of furniture, and in the combination and arrangements of parts, substantially as will be hereinafter more fully described and claimed.

Similar letters of reference indicate corresponding parts throughout the several views illustrated in the accompanying drawings.

Figure 1. is a front elevation of my improved book support, when folded together and turned under a piece of furniture. Fig. 2. is a top plan view of Fig. 1,the folded book support being moved out of the piece of furniture. Fig. 3. is a rear elevation of my improved device, when ready for use. Fig. 4. is an enlarged detail sectional view on the line 00-00 of Fig. 2, and Fig. 5.. is a detail view illustrating a modified form of attaching the support to a piece of furniture.

In said drawings 0. represents the portion of a piece of furniture, to which is secured the bracket 6, having a downwardly extending arm f, carrying cross arms g and an, arranged approximately at right angles to each other. The free ends of said cross arms are provided with semicircular bearings h and z $erial 110.468.443- (No model.)

respectively and the arm galso with a downwardly extending sleeve n, provided with a set screw 0 as clearly shown in Figs. 1 and 3.

Pivoted to the bracketb (as at c) is an arm 01 provided at its free end with a sleeve 6, in which is arranged a tube p, carrying the rod g, which latter can be adjustably secured in said tube by means of the set orthumb screw 15.

Integral with rod q and at right angles thereto is a rod g, on which is adapted to operate a sleeve r provided with a face plate 1, adapted to be guided in the elongated slot r of supporting plate 0 of table 3. (By preference the slot 1" is inwardly beveled and is engaged by a correspondingly beveled screw or projection 7- as shown in Fig. 4.) The face plate ris held in position, when adjusted, by the screw 7", and the sleeve W, on the rod g, by the screw 4". v

The table sis provided at one side with a foot or rest 8 and also with springs s, all these parts being of the usual construction.

In Fig. 5.0f the drawings, I have shown the bracket 1) arranged in an elongated beveled slot of an additional bed plate b in which it is adj ustably secured by means of the thumb screws 12 The operation is as follows: Supposing the book rest and the various parts. occupy the position shown in Fig. 1, that is to say under the furniture and out of position, the rod q is now tiltedupward out of the bearing i and is then pulled outward carrying the tube p through the sleeve e until the end clears the bearing -h on arm g. This position is indicated in Fig. 2. The rest 8, rod q and the tube 19 are then swung around to the right on the pivot 0, until the end of tube is exactly over the sleeve n. Thetube p is then lowered through the sleeve 12 occupying the position shown in Fig. 3. The tube 10 may be raised or lowered in said sleeve n to the required height and held therein by the thumb screw 0. The rest 8 is now drawn outward until the plate 1' sliding in groove 1' of plate 1" reaches approximately the centerof said plate 1", in which position it is held by the thumb screw W. The rest 8 is then tilted on the rod q, until the foot 5 is at the bottom or in the position indicated in Fig. 3. The thumb screw r is then tightened and the rest permanently T D FFICEo held in the tilted position. The rests, rod (1 and its; rod q are then swung around in the tube 13 until the rest is in the required position, in which position it is held by the thumb screw 25..

To return the apparatus to the first position all the movements heretofore describe are reversed.

Should the apparatus when not in use project too far out from the furniture, I have shown at Fig. 5 a beveled bearing b, slidingin a beveled block 12 secured to the furniture, by means of which the arm 61 and the apparatus attached thereto may he slid farther under the furniture if necessary. Thethumb screws b serve to lock the plate I) and prevent its accidental withdrawal from the plate 1).

Having thus described my invention, what I claim as new, and desiretosecure by Letters Patent, is-

1. An adjustable book or music support for chairs, desks and the like, consistingof a rest adapted to be raised, lowered and tilted upon its supporting rod, a standard arranged at right, angles to said supporting rod and adapted to. receive an arm thereof, a bracket secured to the article of furniture, an arm and sleeve pivotally secured to said bracket, said standard being adapted to slidein said sleeve, cross arms depending from said bracket and adapted to receive and support the rest and standard, all arranged so that said supporting rod may be lowered in said standard and said standard, may be swung under the article of furniture and held in said cross-arms when the rest is not in use, substantially as described.

2. The combinatiouin a book or music support for chairs, desks and similar articles of furniture, of the restsand its supporting arm 1 and rod g at right angles thereto, with a tube p pivotally attached to the article of furniture, and the arm f carrying the cross arms 9 and m and also attached to the articles of furniture, said, cross arms being arranged at approximately right angles to each other and provided at their free ends with the bearings h and t, and with a sleevenadapted to receive the tube 19 when the rest is in use, all arranged so that when not in use, therest .9, its

supporting arms q and rod q and the tube 9 may, when the rod of said tube 19 is withdrawn from the sleeve 11., be swung under the articles of furnitmre and be supported thereunder in the bearingsof said armf, substantially as described.

3. An adjustable book or music support for 0 chairs, desks and similar articles of furniture,

consisting of arrest, adapted to be raised or lowered and tilted around a support, a sleeve adapted to engage said support and a bracket to which said sleeve, is pivoted, said bracket being provided with cross arms, said bracket and cross arms being adapted to receive the rest, and its support, when not, in use,.substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 21stday of March, 1893.
